Movie is based on older version Map is not unique like Lavar says, but also it is not copy of another map.This kind of map dont need some special terrain,most of tags have simple terrain
If this is not a copy of another, that is all good for your honor .
Btw the fact that a map doesn't Need a better terrain doesnt change the fact that if you make it better, map will be more pleasant to look at lol.
But if you got another project already, never mind that.
